Definition ∞ Onchain action refers to any transaction, smart contract execution, or data record that is directly processed, validated, and permanently stored on a blockchain’s distributed ledger. These actions are immutable and transparent, forming the verifiable history of the network. They represent the fundamental operations that define the state and progression of a decentralized system.
Context ∞ News often discusses onchain actions when analyzing network activity, transaction volumes, or the usage patterns of decentralized applications. A key discussion point involves the scalability limitations of many blockchains in processing a high volume of such actions efficiently. Future developments will focus on layer-two solutions and sharding techniques aimed at increasing throughput and reducing transaction costs for these fundamental operations.
